directly in line with each other.
1.
Position the pulley in line with the brake pedal arm's
direction of travel — see Figure 2.
2.
If possible, always install the brake pedal clamp as
shown in ‘Preferred Method' in Figure 3, with the slot
in the L-shaped clamp toward the driver's side door,
and with the bend in the L-shaped brake pedal clamp
closest to the firewall.
If there are obstructions or other constraints which
prevent this, the two sections of the brake pedal clamp
can be attached in the following ways…
•
With the slot in the L-shaped clamp (Figure 3) on
either side of the brake pedal arm.
•
With the slot rotated toward the firewall or away
from it (Figure 3).
Additionally, you can further adjust the position of
the clamp by using different attachment holes:
•
The clamp is attached with bolts through two of
the five pre-drilled holes (Figure 3). You can move the
clamp forward or backward on the brake pedal arm by
using different attachment holes.
Additionally, you can trim a portion of the clamp:
•
If more clearance is necessary, you can trim a
portion of the clamp, once you have decided which
two of the pre-drilled holes you will use to attach the
clamp.
Note: InvisiBrake will operate most efficiently with
the clamp as low as possible on the brake pedal arm.
This will generate maximum leverage when InvisiBrake
is activated. Therefore, position the clamp as far down
the brake pedal arm as possible, without interfering
with the normal operation of the vehicle.
Always mount the pulley in line with the brake
pedal's direction of travel, and always mount the
brake pedal clamp as low as possible on the brake
pedal arm. Otherwise, there will not be enough lev-
erage for InvisiBrake to apply the brakes proper-
ly.
This will negate the benefits of the supplemental
braking system.
Make certain that no part of the clamp inter-

full and complete
movement of the
brake pedal arm, as
shown to the right.
Property damage,
personal injury or
even death may
occur if the brake
pedal cannot be
operated at its full
range.

cessible, to an appropriate power source which will be
energized when towing). Since the harness is 15 feet
long, the mounting location should be within 15 feet of
the battery (or power source).
Position the controller at the mounting location you
have chosen, but
do not attach it
— it will be easier
to connect the wiring, air line and vacuum line with the
controller loose.

Position the pulley and both sections of the brake
